Application filed October 23, 1911, Serial No. 656,147. Renewed November 23, 1914. Serial No. 873,637.

To all whom it may concern Be it known that we, THOMAS L. RANDALL and GEORGE W. LEsTER, citizens of the United States, residing at Centerville, in the county of Reynolds, State of Missouri, have invented certain new and useful Improvements in Wire-Fence Clamps; and we do hereby declear the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in fence clamps.

The principal object of this invention is to provide a clamp consisting of a pair of opposed rolls so constructed as to clamp a wire fence therebetween upon rotation of one of said rolls.

Another object of the invention is'to provide a fence clamp including a pair of spaced clamping rolls, one of said rolls being eccentrically mounted to clamp the wirebetween the rolls upon rotation thereof.

A further object of the invention is to provide a clamp of the character described in which the eccentrically mounted roll is detachably connected to the other roll whereby the said clamp may be readily applied to a fence or removed therefrom.

A further object of the invention is to provide a pair of rolls for the purpose set forth in which a novel form of actuating means is employed.

A still further object of the invention is to provide a clamp for the purpose described which is composed of a minimum number of parts, is therefore simple in construction and is cheap to manufacture.

WVith these and other objects in view, the invention consists in the construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim here to appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim may be resorted to with out departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a perspective view of the relatively stationary clamping roll, Fig. 2 is a similar view of the other clamping roll, Fig. 3 is a cross sectional view through the rolls in operation upon a fence wire, and Fig. 4 is a cross sectional view through a pair of modified rolls.

Like reference numerals designate corresponding parts in all the figures of the drawmgs.

Our invention comprises a clamp by means of which the line wires 6 of a fence may be stretched. This clamp consists of a pair of opposed rolls A and B respectively, arranged on opposite sides of the wires and adapted to clamp the same as will be hereinafter set forth. These rolls are preferably formed of wood,'although metal or any other suit able material may be employed. The roll A is normally stationary, and is provided at its ends with metallic caps 77, said caps being fixedly secured to the roll by means of screws 8 or other suitable fastening means. Integral with each cap 7 is a laterally extending projection 9, one of the proections being formed with a rearwardly extending slot 10 which terminates at its inner end in a bearing 11, and the other projection is centrally'formed with a bearing 12. Secured to the inner face of the roll A, and preferably in alinement with the forward edge of the projections 8 is a longitudinally disposed rib 13. This rib is secured to the roll by screws 14 or other suitable fastening means. Centrally secured around the outer face of the roll is a wear plate 15, and passing through this Wear plate and into the roll is the shank of a screw-eye 16, said screw-eye being disposed in a plane at an obtuse angle with respect to the plane of the projections 8.

The roll B is provided at its ends with metallic caps 17-17. These caps are secured to the roll by screws 18 or other suitable fastening means, and projecting laterally from each cap and in alinement with each other are eccentric pins 1919. One of these pins is adapted to be seated within the bearing 12, while the other pin is adapted to slide into the slot 10 and into the bearing 11. It will thus be observed that the roll 13 is eccentrically mounted with respect to the roll A. Secured to the inner face of the roll by screws 21 or other suitable fastening means, is a pair of spaced longitudinally disposed ribs 22-22. These ribs 22 are adapted to be respectively disposed on opposite sides of the rib 13 of the roll A when the roll B is in its operative or clamping relation with respect to the roll A, as clearly shown in Fig. 5. Centrally secured to the outer face of the roll B is a wear plate 23, and projecting through this wear plate and into the roll is the shank of ascreW-eye 24, said screw-eye being disposed in substantially the same plane as the screw-eye- 16 of nected to a lever (not shown) or any other suitable form of operating means.

ln operatlon, When it 1s-des1red to stretch a fence, the rolls are respectively mounted on either side thereof int-the manner pre-v viously described. The links 24 are then attached to the respective eyes andtension is exerted uponthe-chain 25. As a result, the roll; B will be caused to rotate upon its eccentric pins inthe direction of the roll A.

As a result, the wires of the fence will be firmly clamped between the ribs of the respective rolls.

In the modified form of our invention, as illustrated in Fig. 4, there is shown the two rolls A and B respectively. Instead of Tem-v Copies of this patcnt may be obtained for five; cents sac 11,;ibyaaddressingthe ploying the ribs as above noted, the roll A is formed with a longitudinal slot 26, and the roll B with an integral longitudinalbead 29adapted to register With the groove 26,

and thereby clamp and crimp the wire, as

lationitothefirst roller, one of said rollers being. providedv with a .i-longitudinally extending :slot and the other roller beingqtprovided with a longitudinally extending rib adapted to enter said slot, andmeans to row tate saidrollers simultaneously to cause the rib to enter the slot.

In testimony whereof, we affix our signatures in presence =oftwo Witnesses;
